Believe it or not, school is a real life situation. If you are using it in school it real life for you.
No, the product of reciprocals is 1.
If you multiply two reciprocals, their product must be 1.
Every pair of mutual reciprocals has a product of 1 .
Unless you are an electrical engineer or a math teacher, every number you will ever use in a real world situation will be a real number.
I have a feeling that you wrote "opposite reciprocals"where you only needed to write "reciprocals".Their product is ' 1 '.
Well, since there is no such thing as a sphare in the real world, it is a bit hard to tell what it can or cannot use.
If two numbers are reciprocals, then their product is 1. If the product of two numbers is 1, then they are reciprocals.
Yes.
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
use a absolute value to represent a negative number in the real world
Using reciprocals, a/b divided by c/d is the same as a/b times d/c. If you multiply this, you get ad/bc.Without thinking about this as reciprocals, you can do this multiplication directly, cross-multiplication so to speak.
you wouldn't
Many things. Reciprocals, switching spots numerator and denominator. So then it would be 100 over 1. So that is one. Another is if you are changing the fraction to a decimal, you will use 100. If you are simplifying fractions, a denominator of 100 is a good start. A real life problem. Cents out of a dollar.

A bridge
You use fractions for LOTS of things in the real world like money, gambling, shopping, clothing, etc.
